Abstract: The yield and yield components of ginger cv. Bidar local under normal (open) and reduced (shaded) light conditions, and 5 fertilizer treatments (recommended fertilizer rate (RFR) of 100:50:50 kg NPK/ha; 75% RFR + 25% vermicompost; 50% RFR + 50% vermicompost; 25% RFR + 75% vermicompost; and 100% vermicompost at 8 t/ha) were studied in Dharwad, Karnataka, India during 1998/99. Reduced light condition (by 40-50%) was obtained by growing dwarf castor bean cv. Aruna as an intercrop at a spacing of 90x30 cm. The average fresh rhizome yield (11.54 t/ha) and cured rhizome yield (3.64 t/ha) were higher under normal light conditions than under reduced light conditions (6.40 and 1.58 t/ha, respectively). Among the fertilizer treatments, 100% RFR recorded the highest average fresh rhizome yield (10.21 t/ha). The application of 75% RFR + 25% vermicompost resulted in an average fresh rhizome yield (9.16 t/ha) which was almost as high. The effect of the interaction between light intensity and vermicompost on fresh rhizome y
